6 FAQs about [Wind power speed increaser generator assembly]

What type of speed increaser does a wind turbine use?

The speed increasers for WTs can be of fixed-axes [ 3, 14, 15] or planetary type [ 12, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 ], the latter being mainly used to produce high kinematic ratios, as is the case with counter-rotation wind systems [ 23, 24 ].

Can a 1 DOF planetary transmission increase wind turbine speeds?

The performance of a new, patent-pending solution of a 1 DOF planetary transmission is analyzed in this paper, meant to increase the speeds and torques in the counter-rotating wind turbines with counter-rotating electric generator.

Does a wind rotor have a speed increaser?

To surmount the typical incongruence between the wind rotor, which operates efficiently at relatively low rotational speeds, and the electric generator, which has an optimal functioning at higher speeds, a gearbox has to be used as a speed increaser, so as to provide a compatible connection between the wind rotor and the electric generator.

How does a speed increaser work?

Conventionally, the main input of the speed increaser is connected to the main wind rotor R 1, while the secondary input to the wind rotor R 2; the two outputs are connected to the rotor GR and stator GS of the counter-rotating electric generator.

How does a wind turbine speed controller work?

With the action of the speed controller these torques should be equalized at the speed at which the power capture is maximum at the new wind speed. This practically means that the wind turbine speed ωtur must change for the same ratio as the wind speed Vwind, since then the wind turbine power factor Cp will remain at its maximum value.

How does a 1 DOF speed increaser work?

The 1 DOF speed increasers have the properties of summing up the input torques generated by the wind rotors R 1 and R 2, as well as transmitting an independent external motion (in this case, the speed of the main wind rotor R 1) to the other three external links, in a determined way.
